Jupyter spam with "Generating new user for token-authenticated request" in logs – Docker

I have jupyter server runnning in Docker using

FROM jupyter/scipy-notebook

ARG NB_USER

USER root
RUN apt-get update
COPY apt-requirements.txt .
RUN apt-get update
RUN apt-get install -y $(grep -hvE "^s*#" apt-requirements.txt | sort -u | tr 'n' ' ')

COPY requirements.txt .
RUN pip install --upgrade pip
RUN pip install -r requirements.txt
USER ${NB_USER}

here is my .env according to jupyter

NB_USER=lab
CHOWN_HOME=yes
CHOWN_HOME_OPTS="-R"
RESTARTABLE=yes
LOCAL_WORKING_DIR=/home/lab
ACCESS_TOKEN=''
ACCESS_PASSWORD=''

Web-page is working. I’m using nginx with basic auth as an authentication system. But when I’m trying to run any kernel it’s freezed and I see huge amount of the same messages in logs:

could not find any info what does this mean and how to fix it. Does this message affect freezing of kernel at all?

    I was looking at the exact same log message and the one setting in common is the empty token LAB_TOKEN="".
    I just tried a random token LAB_TOKEN="test" and the log spam is now gone on my side. I didn’t have a frozen kernel either way though, so that seems to be an unrelated issue.

    (the following assumes one is using Visual Studio Code to connect to a remote Jupyter kernel — I’m still posting it here in case others find it useful)

    Use jupyter-notebook command instead of jupyter-server to provide the remote API.

    The jupyter-server/ VSCode Jupyter connectivity is horribly broken.
    The latest versions I found which worked:

    • jupyter-server: 1.23.6
    • VSCode Jupyter extension: 2022.6.1001890150 (worked on VSCode 1.77.0)

    Notes:

    • It may be good to rm -rf ~/.ipython ~/.jupyter when experimenting with the server-side versions.
    • My client platform is latest OSX/arm Ventura 13.2.1, server is Ubuntu Server 22.10 x86_64.
    • The way to setup a remote Jupyter connection in VSCode 1.77.0 and Jupyter extension version 2023.3.1000892223:
      1. select "Existing Jupyter Server" and enter the URL
      2. restart VSCode
      3. select "Existing Jupyter Server" and select the previously entered server (which now has a visible entry)
